What a canard. So there was explosion, then it slowed down for a mixing session called a "twist", then a uniform acceleration, without any inherit additional energy or mass to explain this?

Or so it's either Twist, thermodynamics, or p=pm would violate x∆p ≥ ħ/2?

Is this what passes for science now a days? This is about as arcane as saying we all come from The Garden of Eden.

@TheFaustianMan you might wanna watch neil turoks talk from 2008 about the big bang: /watch?v=M9iJMWJdyw8

Producers of "the universe"have asked me to remove all inapropriate comments on these clips, and i have complied. Please do not post dumb comments that are offensive to dr. mainzer or i will have to close the comments section. Thank you for your consideration.

Amy is a lot more than a pretty face.

I wish these clips were in HD. Amy is the best part of The Universe in HD.

@TheFaustianMan That's a strange position to take. Historical figures no less astute and erudite as Einstein and Pauli both basically put in "fudge" factors as purely mathematical constructs to balance their equations that ended up being vindicated for it. This particular model might not be right, but the behavior itself has ALWAYS passed for science. Making testable predictions and passing them being the hallmark of good science afterall.

so the universe is a 2 dimensional entity ?

@bladid

(cont) The answer is "inflation", which arose out of Alan Guth's work while he was trying to figure out something else entirely. His work indicated that the very young Universe went through a period of expansion at far faster than light speed. Thus, the very, very young Universe *was* connected together by light-travel times before inflation separated volumes of space to distances much greater than the light travel time.

@TheFaustianMan It does have a hint of deus ex machina about it, doesn't it? Still, I'm not comfortable with dismissing inflationary theory just because it doesn't seem right to me.

Shouldn't that be "delta x" in your Heisenberg equation? Also, how the hell do you manage to produce the "delta" and "h-bar" symbols on a computer keyboard?????

I am always grateful to hear someone SO brilliant speak, thanks for posting! I am sorry Dr. Kaku, but Dr.Mainzer is much more enjoyable to watch!

[bladid]

fundamentally speaking. yellow and blue not mixing because of the mass of the state before the big bang prevented the two from doing that. but that doesn't mean that'd it have had to be distributed on only one side of the explosion does it? it sounds fishy that the two wasn't shot out everywhere together even though in it's single state. so I'm asking (even though that's only one possibility). why do they explain it like that?

"This would spread green paint all over the universe."

That's a hell of a cleanup job...

Sometimes I think the universe talks down a little much. I mean I love a good visual aide as much as the next guy, but there is a such thing as over simplifying.
